Calcium benzoate (E213) – what is it?
Calcium benzoate, also known as E213, is the calcium salt of benzoic acid. It is a white crystalline powder, slightly soluble in water, which makes it relatively stable and stable as a food additive. This substance is widely used as a preservative in the food industry due to its antibacterial and antifungal properties, which help extend the shelf life of food products by inhibiting the growth of harmful microorganisms.
The safety of calcium benzoate as a food additive has been evaluated and approved by international regulatory bodies, including the European Food Safety Authority (EFSA), meaning that its consumption in acceptable amounts is considered safe for human health.
Properties of calcium benzoate
Calcium benzoate stands out primarily for its preservative properties. It is effective against a wide range of microorganisms, including bacteria, yeast and mold, making it a valuable addition to many types of food products. Due to its chemical stability, calcium benzoate is also preferred in products with high calcium content and in environments with fluctuating pH.
Applications of calcium benzoate
The application of calcium benzoate is versatile. It is widely used in the food industry, including carbonated beverages, fruit juices, dairy products, canned goods and many bakery and confectionery products. Its addition prevents products from spoiling, extending their shelf life and preserving their nutritional value, taste, color and texture.
Where to buy calcium benzoate?
Calcium benzoate is available for purchase mainly through manufacturers and distributors of food raw materials and through specialized food additive stores. It can also be found in the offerings of some online stores that specialize in selling chemicals for the food industry. However, availability in retail stores may be limited.
Calcium benzoate and its functions in food
Calcium benzoate plays a key role in the food industry as a preservative. It contributes to food safety and stability by preventing the growth of microorganisms that could lead to spoilage or contamination. As a result, this additive makes it possible to extend the expiration date of food products without the need for preservation methods that can adversely affect their quality and nutritional value.
